CHUTE FOR PNEUMATIC STACKEFTS.

SPECIFICATION forming part of Letters Patent No. 763,101, dated June 21,1904.

Application filed January 4:, 1904.

T ln/,ZZ wiz/0m it may concern.-

Be it known that I, IIIILLIAM E. J oNns, a citizen of the United States,residing at Fargo, in the county of Oass and State of North Dakota, haveinvented-a new and useful Ohute for Pneumatic Stackers, of which thefollowing is a specification.

This invention relates to pneumatic stacking devices; and it has specialreference to the chute for conveying the material discharged at the tailend of a threshing-machine to the point of deposit.

The invention has for its object to provide and effective in operationand which shall to a large extent relieve the threshing-machine orseparator upon which it is supported from the excessive and injuriousvibration caused by the weight of the discharge-chutes as or- With theseand other ends in view the invention consists in the improvedconstruction, arrangement, and combinationof parts, which will behereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings I have shown of my invention, it beingunderstood, however, thatI do not limit myself to the detailedconstruction therein exhibited, but reserve the right tosuch changes andalterations, especially with regard to size, proportion, and exactmanner of assemblage, which properly come within the scope of myinvention and which may be resorted to without departing from the spiritor sacrificing the utility of the same.

In said drawings, Figure l is'a top plan View of a portion of a chute towhich my invention has been applied. Figs. 2, 3, 4:, and 5 are detailviews illustrating members which enter into the construction of thedevice.

Corresponding parts in the several `figures are indicated by similarnumerals of reference.

In carrying out my invention I employ a plurality of tapering orfrustum-shaped tubular members, of which in the accompanying drawingsfour have been shown, said menibers being designated, respectively, l,2, 3, and 4. One of these members, l, is to be Serial No. 187,691. @lomodel.)

connected by a hinge at the base thereof with a straw-receiver, whichstrawmeceiver 1s connected to therdischarge end of the threshingi 4 isconnected with a discharge-tube 5, only a portion of which has beenshown in the drawings and which may be of any desired length. Themembers 1, 2, 3, and 4 are hingedly connected with each other by meansof bracket members which extend rearwardly or outwardly from the base ofthe first member l, forwardly and rearwardly from the intermediatemembers 2 and, 3, (or as many intermediate members as may be employed,)and forwardly from the last or outermost member 4, the word l rearwardlybeing employed with reference to the direction of the discharge ofmaterial through the chute. The bracket members 6, which connect thefirst and second members 1 and 2, are disposed at the-sides of saidmembers, and the pivotal pins 7, by which said bracket members areconnected, are disposed approximately in a horizontal plane. The bracketmembers 8, which connect the members in rearof the 'first member,aredisposed, respectively, at the upper and lower vsides thereof, andthe pins whereby said members are pivotally connectedsare disposed inplanes at right angles to the connecting-pins 7 or in an approximatelyvertical plane. It follows that while the movement of the member 2 withrelation to the member l is in an approximately vertical plane themembers 2,

3, and 4 are capable of swinging relatively to the bases thereof withoutwardlyfextending lugs l0, having slots or perforations 1l for thereception of connecting-rods 12,'which are disposed intermediate theLhinge-joints which connect the several members, the said lugs IooAbeing connected in pairs by the said connecting-rods. Each of the latteris extended rearwardly of the rear of the lug through which it passesand is provided at its outer end with a nut 14. Tension-springs 15 arecoiled upon said rods between the lugs through which they extend, andadditional springs 16 are coiled upon the rods between the nuts at theirouter ends and the adjacent lugs.

The brackets 6 and 8 and the lugs 10 may be secured directly to thebases of the respective members 1, 2, 3, and 4; but by the preferredconstruction herein shown said brackets and lugs are attached toreinforcing-rings 17, which are riveted or otherwise secured to thebases of the frustum-shaped tubular members. It is obvious that, ifpreferred, the said brackets and lugs may be cast integral with thereinforcing-rings; butinasmuch as such a change would be within thescope of ordinary mechanical skill it has not been speciallyillustrated.

, It is obvious that in any positionoil the chute the springs upon theconnecting-rods serve to take up slack and to prevent rattling andvibration of the hingedly-connected parts. This has been discovered tobe of the utmost importance, inasmuch as it vastly relieves the body ofthe machine to which a device of this kind is usually attached foroperation from the strain incurred by the vibration of the chutesupported thereon, which in practice has been found to rack the machineto such an extent as to cause frequent injuries. With my improvement theordinary vibration of kthe machine while transmitted to thedischarge-chute of the stacker will be taken up by the springs, and theobnoxious effects thereof will be reduced to a minimum.

It is obvious that the number of the hingedly-connected frustum-shapedsections hingedly-connected members having laterally-extending lugs,rods extending through and connecting said lugs in pairs, andtensionsprings upon the said rods.

2. In a device of the class described, tapering tubular members hingedlyconnected and having laterally-extending lugs, rods extending throughand connecting said lugs in pairs, tension-springs coiled upon said rodsbetween said lugs and upon extended ends of the rods, andspring-adjusting nuts upon" the latter.

3. In a device of the class described, tapering tubular members havingbrackets, pins hingedly connecting said brackets, lugs extendinglaterally from the bases of the tubular members, rods connecting saidlugs in pairs, springs upon said rods between the lugs connectedthereby, springs upon the extended ends of said rods, andspring-regulating nuts upon the latter.

4. Ina device of the class described, tapering tubular members,reinforcing-rings at the bases of said members, brackets and lugsextending from said rings, said lugs being disposed intermediate thebrackets, pivotal connecting means for the brackets, rods connecting thelugs in pairs, springs upon said rods between the lugs, springs upon theexy tended ends of the rods, and means for conining said springs.

5. In a device ot' the class described, a plurality of tapering tubularmembers, hingedlyy connected brackets extending from said members andconnecting the latter to swing 1n planes at right angles to each other,lugs extending from said tubular members intermediate the hingeconnections, rods connecting said lugs in pairs, springs upon said rodsbetween the lugs, and springs upon the extended ends of the rods, andsecuring means.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

WILLIAM E. JONES.
